Specification 0f Letters Patent Patented June 2| 1921.

Application filed March `14, 1919. Serial No. 282,675.

To all 'whom it may concern.'

lie it known that I, LAMMnn'r ELENGA, a citizen of the United States, residing at Sterling, inthe county of Johnson and state ot Nebraska, have invented certain new and useful lmprovements in lVindow-Frames, ot which the following isa specification,

This invention relates to windows and wimlowirames and more particularly to that class adapted to be used for sleeping porches. The primary object oi the invention is to provide a mounting fora window sash` by use ot'which ordinary windows of sleeping rooms may be readily converted to those of a sleeping-porch type. Other objects include the provision ot' a window sash which will utilize all of the space within the window frame, for the admission of alr and which may be readily lowered or raised.

Another object of the invention is to provide l a disappearing sash. A further object is to provide a-device. of this class which may he installed while building houses of a conventional type, without altering the architects original plans.

ln the drawing` Figure 1, is a vertical transverse section showing the device mounted in the side wall of a building, the

window sash being in araised position;

Fig. 2 is a similar view to that shown in Fig. 1, the sash being lowered. Figs. 3, 4, 5, 6, 7 and 8 are detail views on an enlarged scale. Fig. 3 shows a Vwindow-sill in transverse section to clearly show a guide, the

slidable auxiliary sill and sash being removed. F ig. 4 is a plan view of a guide. Fig 5 is an end view of the slidable auxlliary sill. Fig. 6 is a plan view of the same, a part being broken away. Fig. 7 is a plan View showing a sash-cap, aside casing strip being shown in section, Fig. 8 is a section through a recess and guide on line 8--8 of Fim lieferring now to the drawing, in which like characters indicate like parts, the invention. is illustrated in connection with the upright side strips 8, the horizontal top strip 9. the sill 10, the sub sill 11 and thedrip sill 12 of a window frame, the apron for supporting the window sill 10 being indicated 'at 13, the parts mentioned for the rectangular window frame being connected in the usual manner. Numeral 14 indicates a window-screen mounted upon the outside of the window frame, which may be employed, if desired. Nu-

meral 15 indicates a single upright window sash adapted to be moved in the groove-16 ot' the side. strips 8 ot' the window traine` said drip-sill being" disposed outwardlyv of u nd adjacent to the sills l() and 11 and the side-strips and grooves heilig of adequate length so that the sash may be moved vertically bctween the drip sill and said sills, l() and l1 and that when the sash is lowered, its upper end will be disposed between and approximately in line with the sills 1l) and 12, at which time it will be seen that all of the operating parts ot' the invention, together with the sash, will not be visible.

ln order that the window sash may be conveniently secured in its uppermost position and that other objects hereinafter to be described, may be attained, l provide a pair of metallic casings or guides 17, each being adapted to be disposed in a. suitable recess a', best shown in Fig. 8, said recesses w being formed in the side strips 8 to open upon the grooves 16 adjacent to the ends of the window sill 10, said guides being secured to the strips 8 by suitable keepers 18 engaging in flanges a and l; of the guides. Nuinerals 19, indicate recesses formed in the sides of the guides to permit a free vertical movement ot' the sash, said casing or guides 17 adjacent to said recesses 19 being provided with flanges c adapted to be secured within the groove 16 by means of suitable keepers 20; and, as clearly shown, each guide is provided at or near one of its ends with a slot s.

Numeral 21 indicates an auxiliary sill adapted to engage in the guides 17 Yand to be disposed horizontally upon `the upper inclined surface of the drip-sill 12 and `upon the inclined surface d of the windowsill 10, and is adapted to have transverse slidable movements thereon, a handle 22 being shown for use when manually moving it.

By referring to Figs. 1, 2 and 6 it will be seen that the lower side of the auxiliary sill is rectilinear, and that its upper "side is formed with a projection o intermediate its faces f and g, said faces being disposed in non-alinement. Numeral 23 indicates a metallic jacket adapted to cover the face q and thel outer edge of the auxiliary/sill, this being desirable since, at times, this partof the sill may be exposed to the weather.

The ends of the auxiliary sill 21 are provided withv extensions l1, best shown in Fig. 6, the metallic jacket 23 covering the ends of said extensions as well as its top surface and outer edge, and caps 24 are employed for covering the remaining part of each end of the auxiliary sill, lugs 25 being employed and each projecting outwardly lfrom a cap 24; and when the auxiliary sill is disposed upon its support, above mentioned, its ends will engage in the metallic guides 17, its lugs 25 engaging in the slots s of the guides.

Numeral 26 indicates a horizontal closurecap or hood which is secured to the top of the sash 15, said cap being provided in its lower side with a recess m. It will be understood that the window may be completely elevated, and the auxiliary sill 21 may then be moved outwardly for supporting the sash as shown in Fig. 1, the lugs 25 moving in the slots s, the metallic jacket g being in engagement with the bottom 'of the sash and projecting outwardly thereof, v said sill 21 operating as a'closure for the opening` between the sills 11 and 12. Also the window sash may be disposed as shown in Fig. 2, the auxiliary sill 21 being drawn inwardly to permit this movement of the sash, the hood or cap 26 covering the parts mentioned and the projection e engaging in the recess m, said hood operating approximately 'to I cover and exclude the parts mentioned from view, and providing a nished appearance, and in a measure, operating to exclude dust.

Numeral 27 indicates a weather strip which is provided for the drip-sill 12 tending to prevent rain from entering the space between the sills, and as best shown in Fig. 1, said strip is adapted to engage the jacket 23 of the auxiliary, slidable 4sill 21 when the latter is in engagement with both of the sills 10 and 12.

Since the slots s are of curved form the auxiliary sill may be moved readily and may have a swinging movement transversely when moved outwardly to the .position shown in Fig. 1 for engagingthe drip-sill, or when moved inwardly of the window frame to the position shown in Fig. 2.

Numeral 28 (Fig. 7 indicates recesses ftion, the scope of which is determined by the appended claims.

What I claim as my invention and desire to secure by Letters atent is In a window construction, a frame provided with a window opening therein, a sash vertically movable in the frame, a main sill 4at the bottom of the frame, a drip sill at the bottom of the frame and spaced from the main sill to provide between the main and drip sills a passage for the sash when lowered out of the frame, a cap piece secured to the upper end of the sash and extending from opposite sides thereof to overlap said main and drip sills and close said passage when the sash is lowered and to provide a smooth surface over the lowered sash, anda shiftable auxiliary sill adapted to be advanced beneath the sash when raised to support the sash and close the passage between said sills, and adapted to be withdrawn from beneath the sash to admit the lowering of the same, said .cap piece and said auxiliary sill having interlocking faces adapted for engagement with one another when the auxiliary sill is withdrawn to retain the sill from displacement, said auxiliary sill being adapted to close the space between the main sill and the cap piece when interpositioned between the same and when the sash is fully lowered.

In testimony whereof, I have aiiixed my signature in presence of two witnesses.
